By ufcfytr, Posted October 17, 2004

Any help appreciated in advance. BRAND NEW crf250x. This bike off idle will bog if you hit the throttle in neutral.

So, off low rpms, wont repsond well, will off higher rmps.

Why is this? HOW DO I GET THE BIKE NOT TO BOG FROM ZERO THROTTLE PLEASE???????????????

Thanks,

Jim

I had the same problem, terrible bog at low speeds and RPM's. I do not know a lot about jetting, but based on what I had read here I bought the JD jetting kit. I followed the instructions and lost the bog. Even though it cost a little the kit sure helped my bike. Good luck with it.

Make sure the bike is fully hot before testing the jetting. A cold bike will bog. Set the fuel screw to be slightly richer than stock and keep the idle speed up.

I bought a 2006 YZ250, have ridden it 5 times. It needs some tuning, but I am not sure I'm keeping it so don't want to spend much on it.
Has fmf gnarly expansion chamber and turbine core silencer.
I ride about 1000 feet above sea level.
I'm going to clean the carb and check the jetting. What is a good jetting for me? 85 main jet?
Also check the reeds. Is there a big difference between getting aftermarket reed cage and reeds or just getting a cheap aftermarket set of reeds that fit the stock cage ie. Boyesen Power Reeds?
The other things I'm going to do is permatex all the joints in the exhaust system and a compression test. It was 220psi 5 rides ago so I'm guessing itll be fine. Its bogging a bit but I'm thinking its carb and definitely exhaust joint related.
Let me know if I'm overlooking anything that could make the bike run crisper and more bottom end without throwing much money on parts
